Intel’s Cascade Lake CPUs Impacted by Newly Discovered Variant of “Zombieload”

Intel’s security nightmare continues. Researchers have uncovered a variant of Zombieload affecting the company’s newest products, which are based on the 14 nm Cascade Lake microarchitecture. Hackers with physical access can exploit this attack (Transactional Asynchronous Abort) to get sensitive data stored in the processor.

Zombieload was discovered by the same researchers who found Meltdown and Spectre, a set of flaws that could be used to pick out secrets — like passwords — from the processor. It was believed later chip architectures, like Cascade Lake, were toughened against speculative execution attacks, while Intel rolled out software patches to reduce the attack surface.
